Similarly, you may ask, what is the difference between epoxy primer and etch primer?
Epoxy primer is catalyzed and self etching is solvent based. Self etching primer bonds well to bare metal surfaces and can be top coated in a short period of time. Epoxy primer can be applied in heavy coats which can be guide coated and block sanded to remove small imperfections in the body.
Likewise, do you need self etching primer on bare metal? Use self-etching primer on bare metal. It will work on just about any metal, whether steel, diecast alloys, or others. The caveat with this type is that you need to remove the old paint and treat the rust ahead of time. If you need to use any fillers like Bondo, apply the fillers before you apply your primer.
Moreover, can you paint directly over self etching primer?
Self-etching primers have to have another primer over the top of them or the paint won't adhere. It can't be an epoxy primer, but it can be a urethane primer. In the meantime, it's important to talk to your paint dealer about the time window allowed between the primer and paint topcoat.
